Thought some of you might be interested to know that Alfa Ricambi is still manufacturing some of the 105/115 Shankle suspension bits...the website's not much help, but they do answer the 800#.
They didn't ever offer super-duper nonstock hardware, but two levels of sport/track springs, sway bars, adjustable upper arms. Plus various Koni etc. shocks. I think 116 sway bar reinforcement plates too.
